The new edition of this book is your guide to learning the ins and outs of the .NET 4 platform and Visual Studio 2010, including: • the Dynamic Language Runtime (DLR) • the Task Parallel Library (TPL, including PLINQ) • the completely revamped WF 4 API • the ADO.NET Entity Framework (as well as LINQ to EF) • the expansion of the Windows Presentation Foundation (WPF) API • improved COM interop If you’re checking out this book for the first time, understand that it targets experienced software professionals and students of computer science—so please don’t expect three chapters devoted to “variable scope” here! The mission of this text is to provide you with a rock-solid foundation in the VB programming language (including a full discussion of OOP) and the critical aspects of the .NET 4 platform. Once you digest the information presented in the book you hold in your hands, you’ll be in a perfect position to apply this knowledge to your specific programming assignments, and you’ll be well-equipped to explore the .NET universe on your own terms.
